S. Korea cuts off beef imports from Colo. plant

GREELEY — South Korea has cut off beef imports from a Colorado meat-packing plant after finding a controversial growth enhancer in the meat.

KUNC reports that the beef in question came from a 22-ton shipment of beef from Greeley, Colo.-based JBS USA. Korean food inspectors found traces of Zilmax. That’s a supplement designed to bulk up cattle before slaughter.

Many European and Asian countries, including South Korea, have banned the use of feed additives like Zilmax. Some say the supplement may be causing the animals lameness or difficulty in moving.

Meatpackers Tyson and Cargill have stopped buying cattle that were fed Zilmax. A few days ago the Chicago Mercantile Exchange put in a place a similar policy.
